Abstract
Polymer coated tin free steel (TFS) cans are being manufactured recently in India. This study was undertaken to evaluate the suitability of these cans for the thermal processing of various fish products. The polymer coating that substitutes the lacquer of conventional tin and aluminium cans was found to be suitable for food contact application. The double seam was examined manually as well as using a double seam analyzer. It was observed that the seal integrity was very good with an overlap of 62%. The cans withstood high temperature and pressure and they do not require over pressure during thermal processing. Sulphur staining was not noticed. Many varieties of fish products were processed in these cans and they were found to be acceptable even after one year of storage at ambient temperature.
